While equipped, the player can use the Neo Chainsaw Mech Arm while piloting their mech to, after a 0.4-second windup, swing the chainsaw downward and produce an energy swoosh. Using the arm again after the first slash swings the chainsaw in the opposite direction, producing a second energy swoosh. Both energy swooshes take 0.3 seconds to launch, pierce through all enemies, and deal 220 damage and 25 knockback. After the second slash, the arm goes on cooldown for 0.6 seconds, producing a total use time of 1.6 seconds, a fire rate of 0.625 two-swoosh combos per second, and a DPS of 275.
